When was the last time you bought butter or margarine?

This question is not quite as simple as it may seem.

When was the last time you bought real butter? When was the last time you bought margarine?

I have not bought margarine for more than 30 years. I only eat margarine at restaurants that give no choice.

I bought butter 2 weeks ago. I like to have a little bit of toast with my butter for breakfast most mornings.
